Hi.  
Just finished migrating Michael H.'s sample app to rails 4 and ruby  
2.  
Everything works great locally, but when i deploy to heroku the app  
crashes and the logs don’t give me anything.

the app: [GitHub - assafshomer/sample\_app: Ruby on Rails Tutorial sample\_app](https://github.com/assafshomer/sample_app)

## the error message in the browser:

An error occurred in the application and your page could not be served.  
Please try again in a few moments.

## If you are the application owner, check your logs for details.

## Heroku logs:

## 2013-05-20T22:13:22.838866+00:00 heroku[web.1]: Process exited with status 0 2013-05-20T22:13:22.853999+00:00 heroku[web.1]: State changed from starting to crashed

HELP PLEASE!!
